Continuum mechanics deals with physical properties of e.g. fluids which are independent of any particular coordinate system in which they are observed.
Our ‘History of Refrigeration’ timeline gives you a brief glimpse into the key milestones of the development of refrigeration and air conditioning
Coolants are heat transfer media which are intended for use below 0°C. Due to its high specific heat capacity, water is often used even below 0 °C. However, pure water already freezes at 0 °C, i.e. the polar water molecules arrange themselves into ice crystals. Glycol as an additive is an effective solution for this
